AUTOMATIC FIRE-EXTING-UISHER.

To all whom it may concem':

Be it known that 1, WILLIAM G. AsMUs, a citizen of the United States, and a resident of Qlevela'nd, inthe county of Cuyahoga and 'State of Ohio, have invented a new and Im proved Automatic Fire Extinguisher, of which the following is afull, clear, and exact description.

This invention is an improved fire extinguisher, relating more especially to automatic sprinklersfor fire extinguishing appa- 'ratus adapted for use in factories, 'ware houses, car storage-houses, car-yards and other buildings, in connection with the water supply thereof, and acting under the abnormal increase of temperature to distribute water, preferably in aspray, in the surrounding space.

More specifically, the invention relates to that special. class of automatic sprinklers wherein a cap or cover normally closes a water outlet or orifice under tension of one or more arms acting to hold the valve on its seat, said arms bein secured together by means of a metal fusi le at a predetermined degree of temperature, and when disrupted by the melting of said metal, releasing the I valve and causing the water to be thrown into the surrounding space.

'The invention has forobjects, among others, to protect the disruptible joint from falling streams of water or other cooling infiuences until such time as the surrounding heat is sufiicient to melt it; also to collect thev heat about the joint as the former rises and provide for the efr'eotive discarding of the displaceable parts when the extinguisher is I thrown into action, whereby they will not interfere with the throwing of the aterto the best advantage.

Reference isto be had to the accompanying drawings forming a part of this specification, illWhlCh similar characters ofjreference I indicate corresponding parts inall the 'fig-' ures ment of my improved fire extinguisher come plete; Fig. 2 is-a vertical, centralysectional view of the same, and Fig. 3 is a horizontal.

Application filed January 4. 1907. Serial No. 350.742.

'' tight j n Figure 1 is a side elevation ofioneiembodi' Patented Dec. 10, 1907.

the open end when the extinguisher is connected with the Water supply, is seated-a cap 3 or other covering, forming a water-tight joint through an intermediate gasket 4 when said cap and nozzle are forced together by the construction hereinafter described.

Threaded on the upper end of the nozzle 1 is a yoke or other equivalent device 5, preferably. formed integral with lugs 6 extending inopposite directions at each side thereof and also with adeflector 6, the latter comprising a dished metal disk, having a series of notches 7 arran ed about its circumference, acting to proper y distribute the water when the cap 3 is released from the nozzle.

Normally arranged between the yoke 5 and seated-on the cap 3, are two substantially L-shaped arms or struts 8, each of said arms having the extremity of its horizontal where they are rigidly connected to'plates which are held together by solder or other fusible metal, providing a fusible joint normally holding the arms from separation.

' It is obvious from the construction this farjdescribed that on screwing the ;w zle'7 into the yoke 5, with the arms or strutgi 8 in engagement with thecap 3 and the lugs 6, as

illustrated, after their upper ends have been solderedftogether, the arms willbe maintained in a vertical position and will force the cap 3 firml to its seat and form a watera1'1ns8 are further assisted in retaining their vertical position, by. a non-corrosive pin 13 embedded in a fusible joint 12 and passing through thecenter of the defleotor'lfi'fj', where eaded portion of the pin is engaged tween it and the nozzle. The.

iti s p horvided with athreaded extiernity 14 "fills t by an'interiorly-tlsreadedprojection'extend;

level than othergextinguishers usedrthe same extinguishing system;.as in car stora ehouses, car-yards or buildings, and in'buiI ings in which it may be desirable to protectautomatic sprinklers from water, acids or other fluids descending from above and which may tend to corrode or in other ways make the fusible joint of the sprinkler inoperative. When thus employed, the hood prevents the water from the more elevated- I In the operation of the exti the nozzle 1, acting on the cap 3, causes the arms to turn on the point 11 as a pivot and separate from each other until they drop by gravity'at each side of the yoke 5. The water from the nozzle then acts directly from the deflector on the hood 15, lifting the latter with the attached pin 13, above the'said deflector and thus effectually dislodgin'g the hood from the rest of the extinguisher. The extinguisher is now. free of the dis laceable parts and the deflector will act to 'stribute the water about in a spray in the surrounding space.

. Although I have described .the. preferred embodiment of the invention in detail in order that its construction and operation might be fully understood, I, nevertheless regard the precise construction as not material provided -.the essential characteristics are employed as pointed out in the annexed claims.

Having thus described my. invention I claim as new and desire to secure by Letters Patent:

1. A iire extinguisher, com rising a tubular body, a cover seated over the outer end of said body, a plurality of arms in engagement at their lower ends seated on said cover near the center thereof, and a single device adjustable on said body in engagement with both of said arms, operable to force the cover down on said body through the intermediary of said arms, whereby the pressure between said cover and tubular body is substantially uniform throughout their contacting area.

2. .A fire extinguisher comprising a nozzle, a cap coveringone end of'the nozzle, a pair of arms in engagement near their lower; ends and having sharpened extensions seated ,on said cap, a fusible joint connecting the upper ends of the arms together, and a yoke threaded on said nozzle in engagement with each of said arms, acting to force the cap down on said nozzle through the intermediary of said arms.

3. A fire extinguisher comprising a nozzle, a cap seated over one end of the nozzle, a pair of L-shaped arms seated on the ca said arms havin upwardly-turned points portions, a fusi le joint connecting .the arms together, and a yoke in engagement with said connected with said nozzle.

4. A fire extinguisher comprising-a nozzle, a cap seated over the upper end of the nozzle, arms seated on said ca ,afusible joint connecting the arms toget er, a yoke threaded on the capyhaving lugs in engagement with said arms acting to force the cap down on said nozzle through the intermediary of the arms, a deflector carried by the yoke above said joint, apin embedded in said joint and passin through the deflector, and a hood ar' range above the deflector and fixed tosaid 5. A fire extinguisher comprising a nozzle, a cap seated on the upper end of the nozzle, a pair of L-shaped arms having pointed exconnecting the upper ends of said arms together, and a yoke having lugs projecting at opposite sides thereof in engagement with said arms, and threaded on said nozzle.

- 6. In a fire extinguisher, a nozzle, means closing the-nozzle seated on its upper end, a plurality of devices seated on said closing means and connected together by a fusible joint, means adjustable on said nozzle in engagement with said devices, and a hood supported from and above said joints.

7. In combination with an automatic fireextinguishrincludin 'a fusible joint, a hood open on its under si e adapted to be automatically displaced by the operation of the extinguisher and normally covering and protecting the same, said joint being located I above the lower edge of the hood, and means connecting the hood and fusible joint together, j I l 8. In an automatic fire extinguisher, a-

said joint and connected therewith adapted to be automatically displaced by the operation of theextinguisher.

In testimony whereof I have signed my name to this specification in'the presence of two subscribing witnesses. j
